INFLUENCE OF MINERAL FERTILIZERS ON PHOSPHOROUS REGIME OF FARINACEOUS-CARBONATE CHERNOZEM AND WHEAT PRODUCTIVITY IN TRANSBAKALIA
Ts. Mangataev, L. Ubugunov, L. Boloneva
Phosphate reserve of farinaceous-carbonate chernozem has been studied. The hosphorus transformation of fertilizers was discovered in soil. There was determined phosphorus removal with the wheat yield as well as coefficients of its utilization from mineral fertilizers. It was stated that its profile distribution in an agrolandscape is connected with chernozem spatial inhomogeneity features.
ABOUT CONDITIONS OF BUCKWHEAT PRODUCTIVITY ENHANCEMENT
Questions of buckwheat productivity enhancement in Siberia are considered. Improper blossom pollination, the lack of root nutrition, and hot weather are the main reasons of seed setting, and therefore, of low buckwheat productivity.
THE STUDY OF PEA VARIETY SAMPLES FROM WORLD VIR COLLECTION IN THE CONDITIONS OF SOUTHERN FOREST-STEPPE OF WESTERN SIBERIA
L. Omelyaniuk, A. Asanov
As a result of the study of the world VIR collection, there were selected pea samples with
economically valuable features and properties. These samples could be the source material at development of new technological varieties in the conditions of Western Siberia.
SPRING WHEAT PRODUCTIVITY ON FALLOW IN FOREST-AGRARIAN LANDSCAPE OF KULUNDA IN VARIOUS VEGETATION CONDITIONS
The influence of weather conditions in vegetation period on the formation of dry biomass yield of plants and grain of spring wheat is stated. The dependence of grain output, photosynthetic potential of sowings, and utilization factor of solar energy by wheat plants on cultivation agricultural engineering and moistening conditions is determined.
REASONS OF MOISTURE PROVISION EXCESSIVENESS OF SOFT SPRING WHEAT IN CHELYABINSK REGION
V. Tiunin, V. Shamanin, E. Chreider
It is shown that reasons of excessive moistening of soft spring wheat expressed by yield depression are crop lodging as well as sowing affection by such harmful diseases as brown rust and carbohydrate protein seed exhaustion. It is disclosed that non-specific complex resistance to these stresses could be enhanced by drought, especially in vegetative period of the culture, and so it depends on tolerance of genotypes to drought. This determines main regional requirements to varieties as well as selection trends.
GROWTH REGULATORS INFLUENCE ON YIELD AND QUALITY OF POTATOES IN WESTERN SIBERIA
It is shown that at leached chernozems of the forest steppe of Novosibirsk Ob region the treatment of tubers and vegetating plants by growth regulators (gibbersib, krezacin, and
novosil) enhances the growth and development intensity of plants. As this takes place, the productivity increases by 25-34 %, the marketability, starchiness and conservation of
potato varieties of different ripeness groups rise as well.
THE USE OF THE LENTAGRAN COMBI HERBICIDE FOR WEED CONTROL IN MAIZE SOWINGS
T. Altukhova, A. Kostiuk, N. Ginevsky
There are presented results of vegetation and field tests of the herbicide Lentagran Combi 36 % KS of the firm Syngenta Crop Protection AG as a weed control agent for maize sowings in the conditions of Primorski Krai of Russian Federation. It is shown that at postemergence application the herbicide in the dose 4,0 l/hectare inhibited effectively annual dicotyledons and depressed, to a certain extent, cereal weeds. Also this herbicide provided increase of the maize corn yield by more than 2 times at the average during the years of tests in comparison with 2,4-DA (1,5 l/hectare) taken as reference. In plant-house conditions it is shown that the herbicide activity of the Lentagran Combi
increased significantly with the soil moisture increase and decreased at application of mineral fertilizers.
PHYTOVERM EFFICIENCY AGAINST SUCKING PESTS OF CLOSED SOIL
I. Andreeva, M. Shternshis
The phytoverm efficiency evaluation was carried out against sucking pests of closed soil for plant protection ecologization in green-houses of Siberia. The preparation efficiency depends on phytophagan species and decreases as the row: red spider, melon and potato aphid, glasshouse whitefly. Number of killed mites and insects was different at different stages of their development. In 1 day after treatment by LK50 for larvae of melon aphid it was 0,16%; for imago it was 0,46 %. The phytoverm efficiency against all phytophagans increases with the concentration rise of working suspension from 0,125 to 1 % and could achieve 100 %.
GARDENING DEVELOPMENT IN ALTAI TERRITORY
A complicated situation taking place in the gardening of Altai Territory is analyzed. This
situation was caused by inconsistent economic reforms in our country. There are noted
concentrations of main garden areas in the Territory farms. It is revealed that specialization deepening and nursery-gardening extension promote collective gardening development.
PHYTOSANITARY SITUATION OPTIMIZATION TRENDS IN SIBERIAN GARDENS
S. Khabarov, L. Shamanskaya
There is shown the importance of garden microclimate, culture rotation, and new
cultivation principles to achieve stable fruiting growth as well as tolerance of perennial cultures to pests and diseases.
STATE AND PROSPECTS OF SCIENTIFIC INVESTIGATIONS ON ARACHNOENTOMOLOGY PROBLEMS
Basic promising trends in veterinary science development in Northern Transural are considered. The complex of theoretical and experimental arachnoentomological investigations directed to the search and elaboration of a new generation of means and methods for control of harmful arthropods and helminthes is described.
BREED FORMATION FACTORS IN REINDEER BREEDING
On the basis of the analysis of ecological and economic factors acting in the reindeer breeding both for a long historical period and now, direction and results of the actual breed formation process in the reindeer breeding are estimated.
PASTURE GROWTH OF HERBIVOROUS FISHES IN POLYCULTURE WITH OTHER SPECIES IN LAKES
The comparison of nutrition spectra of herbivorous fishes at their combined growing in polyculture with whitefishes and carps was carried out. Moderate competition volume is disclosed. On the basis of experimental works in lakes of Tyumen region the optimal planting density of grass carp was calculated for long-term growing. Mass accumulation coefficients for herbivorous fishes obtained as experimental results indicate the need
in revision of existent breed technological growth constants.
COMPARATIVE EVALUATION OF TWO METHODICAL APPROACHES TO CONTROL STUD BULLS OF HEREFORD BREED BY OFFSPRING QUALITY
Results of two scientific economical experiments performed according to different techniques are presented. In the first experiment an estimation of stud bulls allows to select the best ones but in this case there wasn’t possibility to estimate simultaneously more than three stud bulls because of labor expenditures connected with the forage calculation. The second method allows to investigate almost all stud bulls in drove with livestock more than 1,5 thousand heads of cattle and to perform this work yearly.
COST EFFICIENCY OF TECHNICAL MEANS IN RESOURCE SAVING TECHNOLOGIES
N. Yakovlev, L. Yakovleva
The cost efficiency of soil cultivation and cereals sowing is given according both to conventional and resource saving technology using a Lider-8,5. The use of the aggregate Lider-8,5 combined with a tractor K-700 allows to obtain additionally 240–320 t of grain from an area 800 hectares. The cost efficiency is 506 thousand rubles at reduction of factor cost.
SOCIO-ECONOMIC PROBLEMS OF THE AGROINDUSTRIAL COMPLEX OF SIBERIA AND WAYS OF THEIR SOLUTION
The actual state analysis of the Siberian agroindustrial complex is given; the possibilities of its prospective development are determined. There are considered improvement ways for production organization forms, financial and economic sanitation of economies, consolidation of material and technical basis of agriculture, food market development as well as enhancement of rural population style of living.
INVESTMENT ACTIVITY DEVELOPMENT PROBLEMS IN SIBERIAN AGRICULTURE
The investment activity development problems in Siberian agriculture are revealed on the basis of the factual material analysis. Capacity dynamics, investment structure, and reproduction of basic funds in agriculture are investigated. The main trends of investment policy as well as state regulation of investment activity in agriculture sector of economics are determined.
